What You Need to Know
During fermentation, endogenous amylases hydrolyze starches into fermentable sugars, which lactic acid bacteria metabolize to produce lactic acid and reduce pH to 4.5–5.0. Yeasts present on the husks contribute to volatile esters and mild ethanol, adding complexity to the aroma and taste.
The Science
Primary Reaction
Lactic acid fermentation of maize-derived sugars by LAB, producing lactic acid and lowering pH
